To all whom, it may concern.:

Be it known that I, EMnLroUs AUBREY Cox, a citizen of the United States,residing at Humble, in the county of Harris and State of Texas, haveinvented new and useful Improvements in Oil-Burners, of which thefollowing is a specification.

This invention relates to oil or other liquidfuel burners designed foruse in stoves,and has for its objects to produce a comparatively simpleinexpensive device of this character in which the oil supplied to theburner will be thoroughly vaporized before passing to the burner-tubes,one wherein a uniform heating of the fuel is maintained, and one inwhich a supply of vapor will be stored in the burnertubes.

A further object of the invention is to provide a device of thischaracter in which the escape of oil from the burner into the stove isobviated, one wherein a rapid heating of the body of the burner whenfirst ignited is insured, and one in which ready access may be had tothe vaporizing-chamber for purposes of cleaning.

With these and other objects in view the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings, Figure 1 is a sectional view of a stove,showing a burner embodying the invention applied thereto. Fig. 2 is atop plan view of the burner on a larger scale. Fig. 3 is a transversesection taken on the Tine 3 3 of Fig. 1. Fig. 4 is a detail view of theplug or closure. Fig. 5 is detail view of a portion of one of theburnertubes.

Referring to the drawings, 1 designates a stove having a top 2 providedwith pot-holes adapted to be closed by lids 3, these parts, which areconventionally shown herein, being of the usual construction andmaterial.

Arranged within the stove beneath the top 2 is a burner 4, comprising ahollow metal body 5, presenting an internal vaporizingchamber 6 andaplurality, preferably three, of burner-tubes 7, connected forcommunication with the chamber 6 through the medium of suitableoutlet-ports 8, formed in the top wall of the body, which latter isprovided with a projecting marginal flange or apron 9, havinga dished orconcaved upper face 10, adapted to receive an absorbent material 11,preferably consisting of a length of asbestos rope,

there being formed in the bottom wall of the body 5 and centrally of thelatter an opening 12, normally closed by a screw-plug or closure 13,adapted for removal to permit access to the interior of the chamber 6and having lugs or projections 14 for engagement by a suitable tool orimplement for manipulating the plug. Each of the burner-tubes 7 isclosed at its outer end by means of a cap 15 and is provided at a pointsuitably remote from said end with a jet-opening 16, through which thevapor passes for ignition, there being provided in the stove-top 2 atsuitable points above the tubes 7 inlet-openings 17, through which airmay enter to supply oxygen to the Hanne for insuring thoroughcombustion. It is to be observed at this point that owing to the jet-openings 16 being situated remote from the closed ends of theburner-tubes storage compartments or chambers 18 are formed in thelatter for holding a surplus amount of vapor to compensate for anyirregularity which may in the feeding of the fuel arise in practice.

Extending through one of the lids 3 and communicating at its lower endwith the chamber 6 through an inlet-port 19 is a feed pipe or duct 20,leading from a supply-tank 21 and equipped with a controlling-valve22,by means of which the flow of oil may be regulated and controlled, itbeing obvious that the oil will when the valve 22 is opened iow bygravity through the pipe 2O and into the vaporizingchamber 6.

In practice when it is desired to light the burner the oil is turned onand flows through pipe 2O into the chamber 6 and thence through tubes 7for discharge upon the upper face of the body 4, over which it flows andis received in the apron 9 and absorbent material 11, the valve 22 aftera suiicient quantity of oil has flowed into the burner being closed. Theoil held by the apron 9 and asbestos 11 is then ignited and allowed toburn for heating the body 5 and vaporizing the oil contained in thechamber 6, it being apparent that owing to the apron being extendedwholly around the body of the burner and the absorbent material lyingagainst the face of the latter a rapid vaporizing action is insured. Assoon as the oil within the chamber 6 has been convertedinto vapor theburner-tubes 16 are lighted and the valve 22 again opened for feedingthe oil to the chamber, in which it will in turn be vaporized, thusinsuring a constant supply of va- IOO por to the tubes 7. It Will beobserved that owing to the chamber 6 being of elongated form, as shown,and the fact that the oil Will flow in the direction of the leastresistance a proper feeding of the oil to the burner and of the vapor tothe burner-tubes is insured; but in the event of any irregularity in thefeed occurring the vapor contained in the storagecompartments 18 willact as a reserved source to supply the jet-openings and obviateextinguishment of the burner. Attention is 1lirected to the 'fact thatthe absorbent l1 will obviate overflow ot' the oil from the apron 9,and, further, that the plug 13 When removed permits of access beingreadily had to the interior of chamber 6 for purposes of cleaning.

From the foregoing it is apparent that I produce a comparatively simpleinexpensive device admirably adapted for the attainment of the ends inView, it being understood that minor changes in the details herein setforth may be resorted to Without departing from the'spirit of theinvention. I

Having thus described my invention, What I claim is-v In a burner of thetype described, a body having an internal vaporiZing-chamber and aprojecting marginal apron, the latter being provided with an upperconcaved face, an absorbent material arranged in the concaved face ot'the apron, a plurality of burner-tubes connected for communication Withthe vaporiZing-chamber and having jet-openings, and a feed-tubeconnected With the body for supplying fuel to the chamber.

In testimony whereof I aiiX my signature in presence of two Witnesses.
